The mattress' mirapocket spring core, Silentnight’s clever pocket spring variation, offers a tailored sleep experience. The mattress comprises an impressive 1000 pocket springs, with each spring featuring within a fabric sleeve and reacting to individual body movements to apply targeted support and relieve pressure. The other appeal of Mirapocket springs is its ability to distribute weight evenly, ensuring that the mattress doesn’t sag. Moreover, their ‘zero motion’ properties mean a pocket-sprung mattress is ideal for anyone sharing a bed, as your partner’s movements won’t impact your night’s rest. To ensure the mattress's durability, a protective layer sits beneath the pocket-sprung core and disperses air from each of the springs across the mattress's entire surface area.
